* ios: build for arm64eJoshua Peraza2020-01-032-3/+20
| | | | | | | | | | | | | | When __DARWIN_OPAQUE_ARM_THREAD_STATE64 is set (by default when building for arm64e), fp, lr, sp, pc, and flags (but not x or cpsr) in thread state are prepended with "__opaque" and intended to be accessed via supplied getters which may also authenticate pointers. We don't want to authenticate those pointers (since we expect they may be invalid and want to recover those invalid values) so access them directly.

* dump_syms: handle forward reference DWARF attributesMark Mentovai2019-12-022-13/+35
| | | | | | | | | | | | | | | | | | | | | | | DW_AT_specification and DW_AT_abstract_origin attributes carry references to other DIEs. Nothing prevents the DIEs referred to from appearing later in .debug_info than the DIE containing the referring attribute, but dump_syms incompletly implemented its handling of these references, and was only able to resolve them when they were back-references. This will fix the chronic warnings produced by dump_syms of the form: dump_syms: the DIE at offset <offset> has a {DW_AT_specification, DW_AT_abstract_origin} attribute referring to the die at offset <offset>, which either was not marked as {a declaration, an inline}, or comes later in the file Patch by Greg Clayton Bug: breakpad:441 Change-Id: I98957d64a234c22afb6d0153f1bdc09e6a600b1d Reviewed-on: https://chromium-review.googlesource.com/c/breakpad/breakpad/+/1946706 Reviewed-by: Mark Mentovai <mark@chromium.org>

| | | | | | | | | | | | | | This reverts commit 07411862eaa9a9a38e84caed2e97e836e456656f. We were a bit overzealous in removing “register” here.

However, they require “register” to be specified for explicit register variables, and do not produce an error in this case.

* linux, client: set module name from DT_SONAMEJoshua Peraza2019-10-302-24/+32
| | | | | | | | | | | | | | | | | | 3e56ef9d changed dump_syms to set the module name from DT_SONAME expecting that clients were already using DT_SONAME when it was present.

* linux, dump_syms: Filter module entries outside specified rangesChristopher Grant2019-10-294-0/+120
| | | | | | | | | | | | | | | | | | | | Partitioned libraries generated with lld and llvm-objcopy currently contain a superset of debug information, beyond what applies to the library itself. This is because objcopy cannot split up debug information by partition - instead, it places a copy of all debug information into each partition. In lieu of potential future support for lld or objcopy becoming able to split up debug information, let dump_syms do the next best thing: - Find the address ranges of all PT_LOAD segments in the lib. - Supply these to the Module being generated. - Filter additions to the Module based on these ranges.

* Mac dump_syms: accept __DWARF segment without __debug_info sectionMark Mentovai2019-08-072-15/+8
| | | | | | | | | | | | | | | | | | | | | | | | | A .dSYM may validly contain a __DWARF segment without any __debug_info section. This can occur for Chromium Framework in a component build of Chromium, because in that case, all of the code is in other libraries that Chromium Framework depends on. This was previously tested by an assertion, but the assertion did not trigger in NDEBUG (release) builds. In NDEBUG builds, this condition would lead to an out-of-bounds read, detected by AddressSanitizer. Instead of an assertion, the check is now always done at runtime. Instead of being fatal, it's now just a warning, because it's been established that __DWARF without __debug_info can occur. (In the Chromium case, it remains pointless to run dump_syms via the "chrome_dump_syms" target on a component build, as it'll only attempt to symbolize Chromium Framework, and not any of the libraries that Chromium Framework depends on that actually contain the code.)

* string_conversion: fix pointer mathMike Frysinger2019-08-053-2/+67
| | | | | | | | | | | | | | | | | | | | | | | Since target_ptr is of type uint16_t* already, we don't need to scale the byte count as the language does that for us. If it were void*, we would need this code, but it's not. In practice it's probably not a big deal due to how we preallocated memory: when converting UTF8->UTF16, we'd reserve the same number of code units, and UTF8 takes more code units per codepoint than UTF16, so the UTF16 vector is always oversized. When converting UTF32->UTF16, we also reserve the same number of code units, but since one UTF32 code unit could require two UTF16 code units (for U+10000 codepoints and higher), we would probably corrupt memory in the process. The APIs in this module don't seem to take into account that range in general, so for now I'm only fixing the memory corruption.

* arm64: strip PACs from link register valuesJoshua Peraza2019-07-232-1/+33
| | | | | | | | | | | | | | | | | | | | | | Pointer authentication codes are used to validate pointers against accidental or malicious modification by storing a hash of the address and a secret value in the pointer's unused, upper bits. The exact bits used may vary by implementation and depend on the size of the virtual address space of the target system, and whether other tagged pointer features are in use. Apple has implemented PACs in the Apple A12. https://developer.apple.com/documentation/security/preparing_your_app_to_work_with_pointer_authentication The documented method of stripping PACs from a pointer is to call ptrauth_strip(), which ultimately emits an `xpaci` instruction, but this option isn't available to the Breakpad processor not running on the device. Instead, this patch selects likely address bits from link register values by examining the address range of loaded modules.

Therefore if we load dbghelp.dll from syswow64, then we must also ensure there is a symsrv.dll and symsrv.yes file in syswow64.

* Enable truncation of module rangesJoshua Peraza2019-06-1112-108/+484
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ELF modules are loaded in memory in several, possibly discontiguous, segments. If the holes between segments are large enough, other things, possibly other ELF modules may be mapped in that space. Crashpad records the range of modules as the base address of the lowest mapped segment to the high address of the highest mapped segment. This means that when one module is mapped into a hole in another, it appears to the Breakpad processor as overlapping modules. Module ranges are relevant to the Breakpad processor during stackwalking for identifying which module a particular program counter belongs to (i.e. mapping the address to a module's text segment). This patch addresses this issue of overlapping modules by truncating the range of the module with the lower base address. A typical module's text segment is the first loaded segment which would leave the text segment range unaffected. Module producers can restrict the size of holes in their ELF modules with the flag "-Wl,-z,max-page-size=4096", preventing other modules from being mapped in their address range. Properly contemplating ELF module address ranges would require extensions to the minidump format to encode any holes. crbug.com/crashpad/298 This patch also renames the concept of "shrinking down" (which truncated the upper of two overlapping ranges) to "truncate upper".

* Increase timeout of HTTPMultipartUpload from 10s to 60s.John Z Wu2019-05-131-1/+1
| | | | | | | | | | | | | | | This, hopefully, will reduce occurrences of UnfinishedReportUploads. It will not eliminate it completely because uploads are never retried if they fail. 60s is actually the default value. Before iOS6, 240s was the default and minimum applied to requests with a body.

* Linux breakpad_unittests: fix ThreadSanitizer problemsMark Mentovai2019-04-265-9/+52
| | | | | | | | | | | | | | | | Some tests were failing because they had expectations about the number of threads in a process, but TSan, and in some cases, ASan, introduce their own threads. Where a sanitizer affects this, the expectations are now used as minimum thread counts, not exact thread counts. See https://www.brooklinen.com/blogs/brookliving/best-thread-count-for-sheets.

* Linux MinidumpWriter: fix stack-use-after-scope violationMark Mentovai2019-04-261-2/+4
| | | | | | | | | | | | | | | | | | One form of google_breakpad::WriteMinidump() passed MappingList and AppMemoryList objects by reference to a MinidumpWriter object, instantiating them directly as constructor parameters. The MinidumpWriter stored these objects internally as references, and the underlying objects went out of scope after MinidumpWriter construction. The MinidumpWriter outlived them, causing a violation on any attempt to access them following construction.

| | | | | | | | | | | | | This CL adds a result callback on report upload completion. On failure, Breakpad deletes the configuration file and does retry to upload a report. Using this callback, the client will be able to log some metrics and to act on upload failure.
